SEWING-MACH Application filed September This invention relates to binderattachments for sewing machines of the kind in which a strip of materialis folded and fed 1n a direction at right angles to its initialdirection of feed and in which the raw edges of the bindng strip arefolded over in readiness to be stitched to the material to be bound,whereby the necessity of first preparing the binding strip with itsedges turned and pressed down is avoided.

Binders of this character have heretofore been proposed in which a baseplate is removably secured, with capacity for adjustment, to the bedplate of the machine and supports the binder attachment which embodies afolding plate formed with an axial rib merging into a flat receivingspace and having flanges formed with inwardly turned lips or wings toenclose a guide tongue cooperating with the plate whereby the bindingstrip may receive a W-shaped cross-section. At the extreme delivery endof the plate the flanges have been formed with inwardly and rearwardlyextending tongues which extend across the adjacent end edge of the guidetongue. Such a folding plate as heretofore used has, of n cessity, beenformed of such relatively thick sheet metal, in order that it may holdits shape in use, that it has not been possible to give the plate therequisite compound curvature to properly fold a binding strip with thegreatest efficacy, especially if the strip is of a soft material; andwire and loops have also been provided on the delivery end of theflanges to form inwardly projecting edges therefor which are not durableand involve a manual operation which has been found difficult, requiresconsiderable time and generally results in an unsymmetrical formation,no two wires being alike when aflixed.

The present invention seeks to avoid the impractical featureshcreinbefore discussed by the provision of an outer shell member ofsimple construction but of sufficient strength to adequately reenforce,when assembled therewith, a folding plate formed of sutiiciently thinmaterial that it can be given the requisite curvature. This shell memberalso has formed thereon, by a die, in a stamping operation small fingersbent on the delivery end which, when the device is assembled, lie inspaced relation with the ends of the forming plate and guide tongue. Theflanges are bevelled at the delivery end and recede from the fingerswith a gentle curvature to form what is in effect channels or guidesfrom the INE BINDER.

grooves in the folding plate to the notch therein from whence the foldedmaterial is directed at right angles to its previous direction oftravel. With the construction just described it is possible to adjustthe tape backwardly in case of non-sewing.

Heretofore the base plate which supports the binder has been removablyand adjustably secured to the bed plate of the machine by screws or thelike and by such construction the adjustment of the guide with respectto the needle has involved considerable skill, time and labor as well asnecessitating the use of tools. The present invention seeks to provide aliner adjustment of the guide with respect to the needle by what may betermed a micrometer adjustment wherein no tools are required. Moreparticularly, the adjusting devices take the form of a pivoted leveroperatively connected to the base plate eccent-rically of the pivotwhereby movement of the lever about its pivot will cause movement of thebase plate to or away from the needle in a lesser degree, obviously,than the movement of the lover.

The invention also has to do with a convenient method of mounting thereel from which the tape is supplied to the binder in conjunction withthe binder attachment whereby both binder and reel may be handled as aunit. To this end the reel is carried upon the extremity of theadjusting lever or an extension thereof.

The invention further has for its object to provide a binder attachmentwhich shall be practical from the standpoint of convenience, ease andcheapness in manufacture and durability in use. To this end thecomponent ele ments of the binder are formed of stampings which may besoldered together to form an operative whole.

These and other objects of the invention and the means for theirattainment will be more apparent from the following detailed descriptionof a preferred embodiment thereof which is illustrated in theaccompanying dra ings and in which:

Figure 11 is a view looking from above in Figure 10 and showing the clipof that figure.

Referring to Figures 1 and 2 the bed plate 1, of a sewing machine isadapted to be secured thereto in any convenient manner as by screws iassng through the apertures 2. The bed plate 1 is also provided withcustomary aj'iertures 3 and 4 as will be understood and an eye 5 for aneedle. A presser foot is indicate'cl in broken lines at 6. A base plate7 having an upright bracket plate 8 along its edge is ordinarily securedas by a or the like to the bed plate 1. In the illustrated embodimentthe bed plate is formed with a groove 9 adapted to receive a flange 10formed on the rear or lower face of the base plate 7. The base plate 7is also formed with an elongated aperture 11 having a recess 12 at oneside thereof. Immediately above th 1* base plate there is disclosed alever 13 pivo ally mounted upon the bed plate 1 by a screw 14 passingthrough the elongated aperture 11 in the base plate and threaded into ahole 15 in the bed plate of the machine. The lever also carries on itsunderside a lug l6 ent ring the recess 12. This lug is eccentric withrespect to the pivot 14 whereby movement of the lever 13 about its pivotwill cause movement of the base plate 7 with respect to the groove 9thereby moving the base plate n arer or further away from the needle eve5.

Carried upon the projecting bracket plate 8 is the folding device orhinder according to the present invention. The folder is formed of aplurality of component elements illustrated in Figure l throu trh ll.Directly eecured as by soldering or the like to the upright bracketplate 8 is an outer shell member indicated as a whole at 17 having aplain rear surface 18 turned slightly outwardly and rearwardly at thereceiving end as at 19. At the delivery end the shell member is formedwith a notch 20 and adjacent the delivery end are carried flanges 21rounding gently outward and provided respectively with inwardly directedtongues 22. The delivery end of the flanges are bevelled from thetongues 22 to the sides of the notch 20 and terminate in fingers 23extending into the notch portion in substantially the plane of the rearsurface 18.

The folding plate shown at Figures 6 and 7 is indicated as a whole at24. It is formed of very thin sheet metal by dies so that it may begiven the proper gradations of curvature to permit it to fold even thesoftest of materials in a perfect manner. It is because of the lightmaterial of which it is formed that the shell member is utilized to giveadequate strength and rigidity to the folding plate after it is formed.The folding plate is formed at the receiving end with a substantiallyflat receiving face 25 having an outwrrdly and rearwardly deflectedflange 26 which, when the folding plate is assembled upon the outershell member adapted to overlie and engage the end 19 of that member. hefolding plate is formed with an axial rib 27 which merges into thereceiving face 25 and is relatively high and narrow at the dclivery endand deeply notched as at 28. Adjacent the receiving end the foldingplate is formed with side flanges 29 teri'ninating in wings 30 which.adjacent the receiving end, are substantially parallel with thereceiving face 25 but which converge with respect to the flange 29 asthe axial rib increases in height. At the delivery end the folding plateis also formed with flanges 31 which rise sharply from the axial rib toform acute angle grooves or troughs 32. The flanges 31 after divergingfor an appreciable distance from the axial rib to form in general a Wcross-section are turned inwardly and rearvardly as at 33, to serve aspositioning means for a guide tongue hereinafter to be c escribed.Closing the notch formed by the rib 27 at the delivery end is a U-shapedflange 34 perpendicular to the plane of the paper as viewed in Fig. 6and shown clearly in Figure 7 as extending beyond the rear marginal faceof the folding plate. This flange is adapted when the folding plate andouter shell member are in assembled relation to extend within the notch20 of the shell member and with the flange 26 facilitate the positioningof the two elements.

The guide tongue 35 is illustrated in Figures 8 and 9 and is formed atthe receiving end with a substantially flat face 36 and a start feedslot 37 midway between the ends. At the delivery end the tongue isnotched as at 38 to cooperate with the notch 28 of the folding plate.The tongue is curved transversely to cooperate with the axial rib of thefolding plate as will be understood. It is also formed with a bevelledreceiving end shown clearly in Figure 9 at 39 which receiving end isadapted to lie closely adjacent the wings and to be held against saidwings by means of the clip illustrated in Figures 10 and 11. Since thetongue and folding plate are both formed of very thin sheet metal inorder that hey may assume the requisite curvature, the clip all) isavailed of to secure the ends together and reenforce them with the aidof solder to produce a stilt construction at the receiving end. Thisclip is U-shaped in crosssection as shown in Figure 11 at 41 and between the arms of the U-shaped portion are adapted to be received theends 36 and wings 30. Side elements 42 are formed at the ends of theU-shaped portion to overlie and reenforce the side flanges of thefolding plate as will be understood from an inspection of Figures 1 and2. p

in the assembly of the device the folding plate and guide tongue may befirst assembled, the wings 30 and serving to pos. on the tongue withrespect to the axial rib. The

tongue may then be secured to the folding plate by the clip l0 andsolder may also be availed of to further secure the two in operativeposition. The outer shell member and folding plate may then be assembledwith the flange 26 overlying the edge 19 of the shell member and theflange extcndii within the notch 20, the tongues 22 overlying the wings323 with the bevelled edges of the flanges 21 in spaced relation withrespect to the delivery end of he folding plate. After the componentelements of the device have been suitably secured together the rear faceof the outer shell member is secured to the front face of the uprightbracket member carried iih the base plate as clearly shown in Figures land 2.

As the folding device or binder is directly carried upon the base plateand the base plate is capable of adjustment \Vlkll respect to the needleeye 5 it follows that the binder is thus readily adjustable with respectto the needle eye without necessitating the use of a screw driver orother tool in the making of the adjustn'ient.

Referring again to Figures 1 and 2 it will be observed that the lever 13is fo aned with an extension 43 carrying a pin i l at its extremity uponwhich is adapted to turn a reel 45 carrying the binding tape 46.

It will thus be seen that a binder attachment has been provided which ispractical from the standpoint of manufacture and use. The constructionprovides for a guidanre of the tape which facilitates its adjustment ina reverse direction in case of failure of the sewing device to properlysecure the tape to the material to be bound. Exact adjustment of thebinder with respect to the needle is also possible with the deviceaccording to the present invention in a simple, convenient andexpeditious manner, while the reel carrying the tape is so mounted as tobe a part of the attachment and capable of removal with the bindingattachment as a unit.

It is to be understood that the various features hereinbefore enumeratedare capable of independent use although mutually eontributing to thedesired end and no limitation is intended in the configuration andassembly according to the foregoing description and illustrations exceptas indicated in the accompanying claims.

Having thus described my invention I claim 1.
